Next, the operation of the deodorizing device will be described together with the method of use. As shown in FIG. 6, this deodorizing device is used by being attached to a wall W of a toilet or kitchen, for example. This device 1
In the operation of 0, after confirming that there is sufficient deodorant liquid in the deodorant liquid container 20 in order to prevent empty cooking, the power switch 15 is pressed to turn on the power. Then, a blower (not shown) is driven to suck the air Y into the inside of the apparatus through the air inlet 12b and blow out the air X from the outlet 14, and at the same time, energization of the heating element 18 is started to generate the heat. The body 18 generates heat and the metal member 23 of the suction core 22 is heated. After a while, when the temperature of the metal member 23 reaches a predetermined temperature, evaporation of the deodorant liquid on the upper portion of the suction core 22 starts. The vapor of the evaporated deodorant is blown out from the blowout port 14 by the air blown from the blower, and spreads throughout the room such as a toilet or kitchen.

In this state, for example, when the deodorizing device 100 is attached to the upper part of the wall of the room R as shown in FIG. 8 (a), the components of the deodorizing agent spread as shown in the figure, and the deodorizing device is spread. Deodorization is performed sequentially from the portion close to 100. The mechanism of this deodorization will be briefly described below.

FIG. 8 (b) is a portion A of the room R in FIG. 8 (a).
Are enlarged and shown. As shown in FIG. 8 (b), when the deodorant component (deodorant vapor) e comes near the odorous component S drifting in the air, these are sequentially discharged around the odorous component S. The deodorizing component e is linked to and surrounded by the deodorizing component e, and finally the odor component S is wrapped in the package E. As a result, the bad odor caused by the odor component S is completely eliminated.

When operating the above deodorant device, the deodorant can be effectively used without waste by adjusting the transpiration amount with the adjusting knob 17 according to the degree of the bad odor. By setting the knob 16 at a predetermined time, it is possible to continuously operate for a predetermined time. When the amount of the deodorant remaining in the deodorant liquid container 20 is getting low, the operation is temporarily stopped, and then the deodorant liquid container 20 is removed from the apparatus body 11 to remove the deodorant liquid 22.
Is replaced with a new deodorant liquid container, and this can be attached to the apparatus main body 11.

[0013]

However, in the conventional deodorizing apparatus, the deodorant is evaporated by the heat of the heating element 18 and the core 22 is heated. If the deodorant becomes empty, the wick 22 will be cooked empty. In this case, the temperature of the suction core 22 becomes abnormally high, which may damage the suction core 22 or the entire apparatus 11, and in the worst case, it may cause a fire.

Further, since the evaporation of the deodorant is carried out by heating, the deodorant may be deteriorated by heat, and it may not be possible to exert a good deodorant effect. Furthermore, the deodorant only evaporates from the narrow exposed portion of the upper surface of the suction core 22, and the evaporation amount of the deodorant per unit time may be due to the increased heating temperature. Therefore, there is a problem that a certain amount of time is required even when the bad odor in the room is so severe that it is desired to deodorize it immediately.

The present invention has been made in order to solve the above problems, and can fully bring out the deodorizing effect without causing deterioration of the deodorant due to heat. It is an object of the present invention to provide a deodorizing device that does not cook even if the inside of the container becomes empty and that can adjust the evaporation amount of the deodorant per unit time in a wide range.

This control unit 180 uses the transpiration amount adjustment knob 107 and the timer knob 1
When the transpiration amount adjusting knob 107 is adjusted, the drive currents of the pump 150 and the motor of the blower are changed in conjunction with each other, and the deodorant vapor diffused in the air. The amount of can be adjusted.

Here, a circuit configuration for performing the interlocking adjustment of the control device 180 will be briefly described with reference to FIG. In the figure, reference numeral 190 is a household AC power supply.

The control device 180 has a built-in timer function as in the conventional device, and the function can be adjusted by the timer knob 106. In the apparatus of this embodiment, the power on / off button 1
05 is located slightly closer to the center than the conventional device.

Next, the operation and its usage will be described. Like the conventional device, this device is also used for deodorizing a kitchen or toilet of a general household, and is used by being attached to a wall W of a room or the like.

As in the case of the conventional apparatus, when the power switch 105 is pressed to turn on the power after confirming the remaining amount of the deodorant liquid, the compression pump 150 and the blower motor 130 are driven. At this time, since the deodorant liquid is introduced into the bubbling container 110 from the deodorant container 140, the porous member 14 on the bottom surface of the bubbling container 110 is immediately formed.
Bubbles are generated from 0, and the deodorant liquid is bubbled. The deodorant thus vaporized enters the upper space 101a through the sponge member 113 of the lid member 112 of the bubbling container 110. At this time, the blower fan 120 causes the external air X to suck the intake air 1
03 is sucked to the blower fan side, the vapor Z of the deodorant is also sucked into the fan 120 along the flow of this air, and the air Y containing the vapor of the deodorant is blown by the fan 12.
It is discharged to the outside from the outlet 104 on the front surface of No. 0. In this way, the deodorant liquid vapor is evaporated throughout the room such as the kitchen to deodorize the room. The mechanism of this deodorization is the same as that of the conventional device, and is omitted here.

Further, the adjustment of the deodorizing ability during the operation of the deodorizing device is as follows.
This is performed by rotating the transpiration amount adjusting knob 107 of the control device 180 to the transpiration amount increasing side or decreasing side.
That is, by rotating the adjusting knob 107, the movable contacts 130a ₁ and 15 of the variable resistors 130a and 150a are rotated.
0a ₁ slides in conjunction with each other, which causes the resistance value of the resistor to change, which in turn causes the rotation speed of the blower motor and the air pressure feed amount of the pressure feed pump to change, resulting in adjustment of the transpiration amount. Done. Since the operation of the timer knob 106 is the same as that of the conventional device, its explanation is omitted.

When the amount of the deodorant liquid in the deodorant container 140 becomes low, the container 140 is replaced with the apparatus main body 101.
The lid member 141 is pulled out from the inside of the casing 101 of a, and the lid member 141 is replaced with a new container containing the deodorant liquid, and the lid member 141 is mounted in the apparatus main body.

As described above, in the present embodiment, the evaporation of the deodorant liquid 300 is introduced by introducing the deodorant liquid in the deodorant container 140 into the bubbling container 110, and air is blown into the deodorant liquid to bubble. Since the deodorant is evaporated by heating, unlike the conventional apparatus, the deodorant effect can be sufficiently brought out without causing deterioration of the deodorant due to heat. Further, the power consumption can be greatly reduced as compared with the case where the deodorant liquid is evaporated by heating.

Since no heating element is used, the apparatus 100a
Even if the deodorant liquid inside becomes empty, the suction core is not boiled like the conventional device, and therefore there is no risk of damage or fire due to heating of the device body. This is because the conventional device requires a circuit configuration that detects the liquid surface of the deodorant liquid and stops heating when the remaining amount of the deodorant liquid is low in order to prevent damage due to heating. On the other hand, it can be said that such a circuit configuration is unnecessary and it is advantageous in terms of the manufacturing cost of the device. Furthermore, in the evaporation by bubbling, the vapor of the deodorant is generated not only from the liquid surface but also from the inside of the deodorant liquid, and the evaporation amount per unit time is adjusted by adjusting the amount of air sent into the liquid. Can be adjusted in a wide range.

Further, since the controller 180 is equipped with an adjusting circuit for adjusting the blowing amount of the compressed air into the bubbling container 110 and the blowing amount of the blower fan 120 by one adjusting knob 107, the deodorant liquid. The amount of transpiration can be easily adjusted.

Further, the deodorant container 140 and the bubbling container 1
10, the compression pump 150, the blower fan 120 and its drive motor 130, and the pump 150 and the motor 130.
Since a control device for controlling the drive current of 1 is incorporated in one housing 101, a deodorizing device which is small and compact and which is very easy to handle especially in a general household can be obtained.

Further, since the deodorant 300 is a solution containing a green tea extract as a main component, the malodorous component s floating in the air is wrapped by the component e of the deodorant, and the malodorous substance Can be completely deodorized.

Next, a second embodiment of the present invention will be described. FIG. 5 is a diagram for explaining the second embodiment of the present invention. This deodorizing device is replaced with the wall hanging type of the above embodiment,
It is a floor layout type that is placed in the corner of the room where deodorant is performed. In the figure, reference numeral 200 denotes a deodorizing device of this embodiment, which has a blowing port 204 for deodorant vapor on the upper surface of the device main body 200a.
Further, a transpiration amount adjusting knob, a timer knob and the like are also arranged on the upper surface of the apparatus main body, and an opening for inserting and removing the deodorant container is formed on the upper surface of the apparatus main body 200. Has been done. For this reason, in this device, a lid member that covers the knob and the opening for taking in and out of the deodorant container is also attached to the upper surface of the device body.

Further, the arrangement of each component inside the apparatus main body is the same as that of the first embodiment except that the arrangement of the control device for adjusting the compression pump and the blower motor is changed to the upper portion in the housing. It is almost the same. The second embodiment having such a configuration also has the same effect as the above embodiment.

In each of the above embodiments, the control device 1
As a transpiration amount adjusting circuit of 80, a transpiration amount adjusting knob 170
The configuration is shown in which the amount of compressed air blown into the bubbling container 110 and the amount of air blown by the blower fan 120 are changed in association with each other by the rotating operation of. The circuit and the adjustment circuit for adjusting the air flow rate may be independently configured, and the adjustment may be performed by the respective separate adjustment knobs.

In the above description, the deodorizing device has been described in which the deodorizing liquid is evaporated by bubbling.
The method of evaporating the deodorant liquid is not limited to this, and any method that does not use a heat source may be used. For example, the deodorant liquid may be evaporated by ultrasonic vibration.

The third embodiment of the present invention having the above construction will be described below. 9 and 10 are diagrams for explaining the present embodiment. FIG. 9 shows the circuit configuration of the control device, and FIG. 10 shows the internal configuration of the evaporation container. This device is the same as the device of the first embodiment, except that a container 111 for evaporating the deodorant liquid is replaced with a porous member for bubbling, and ultrasonic vibration is applied to the deodorant liquid in the container. A liquid level sensor 2 for arranging a sound wave oscillator 250 and detecting the liquid level of the deodorant liquid at a predetermined height position on the inner surface of the container 111.
70 is attached, and the ultrasonic transducer 250 and the blower motor 130 are controlled to be turned on / off in accordance with a signal from the sensor. Other points are the same as in the first embodiment.

Here, the ultrasonic vibrator 250 accommodates a vibrating piece 252 which vibrates by applying an AC voltage in the housing 251 to generate ultrasonic vibration, and from the vibrating piece 253, a voltage applying conductor 253. Further, although the internal structure of the liquid level sensor 270 is not shown, this is so that the contact of the switch opens and closes based on the movement of the floating member that moves up and down depending on the liquid level. It was done.

Further, in this embodiment, the circuit configuration of the control device 180 is, as shown in FIG. 9, between the AC power source 190 and the variable resistor 150a, instead of the pump 150 of the first embodiment, an ultrasonic transducer 250. By adjusting the transpiration amount adjusting knob 107, the applied current to the ultrasonic transducer 250 and the drive current of the blower motor are changed in conjunction with each other, and the deodorant diffused in the air is eliminated. The switch 2 is provided so that the amount of the vapor of the agent can be adjusted and between the AC power source 190 and the blower motor 130 and the ultrasonic vibrator 250.
60 is arranged, and the opening / closing control of the switch 270 is performed based on the liquid level detection signal from the liquid level sensor 260. Here, when the liquid level in the evaporation container 111 is above the liquid level sensor 260, the switch 270 is closed, and when the liquid level is below the switch 2
70 opens.

As described above, in this embodiment, since the evaporation of the deodorant liquid is performed by applying the AC voltage to the ultrasonic vibrator 250 arranged in the evaporation container, the pump for evaporating by bubbling is used. There is no need, and the structure of the deodorizing device can be simplified as compared with the first embodiment, and the simplification of this structure has the effect of facilitating maintenance work.

As described above, according to the deodorizing apparatus of the present invention, the liquid deodorant is evaporated, the deodorizing liquid is bubbled, or ultrasonic vibration is applied to the deodorizing liquid. Since it is performed by doing so, unlike the evaporation by heating as in the conventional device, the deodorizing effect can be sufficiently brought out without causing the deterioration of the deodorant due to the heat, and the heating element is not used. Therefore, even if the deodorant in the device becomes empty, it does not boil the suction core unlike the conventional device, and there is no risk of damage or fire due to heating of the device body. .. Furthermore, in the vaporization by bubbling or ultrasonic vibration, the vapor of the deodorant is generated not only from the liquid surface but also from the inside of the deodorant liquid, and by adjusting the amount of air sent into the liquid,
There is also an effect that the evaporation amount per unit time can be adjusted in a wide range.

Further, since the adjusting circuit for adjusting the blowing amount of the compressed air, the magnitude of the ultrasonic vibration, or the blowing amount of the blower is provided, the evaporation amount of the deodorant liquid can be changed according to the degree of the bad odor. The amount of transpiration can be adjusted easily by adjusting the amount of suction and the amount of ultrasonic vibration and the amount of blown air in conjunction with each other.

Further, a sensor for detecting the liquid level of the deodorant liquid is provided in the evaporator, and the compressed air is blown or blown when the liquid level falls below a predetermined level based on the detection signal. Since the generation of ultrasonic vibration and the blower of the blower are stopped, it is possible to prevent wasteful power consumption after the deodorant liquid becomes empty, and prevent the harmful effects due to overheating of the ultrasonic vibrator. There is an effect that can be done.

Further, since the components of the deodorant storage tank, the evaporator, the blower, and the like are incorporated in one case, the deodorant storage tank is small and compact, and is especially easy to handle in general households. A simple deodorizing device can be obtained.

Further, since the solution containing green tea extract as the main component is used as the deodorant, the malodorous components floating in the air are covered by the components of the deodorant, and the malodor is completely eliminated. There is also an effect that can be deodorized.
